In the forms shown in Figs. 4 to ti, the llango '26 projects from the base of tho ring 25 in a similar manner to the lirstform, but in this instant-o the [n'ojcuting llango 26 is provided with upright sido flanges or walls .27, hirh prolerably project buyout. the plane of the top of the ring .25, as at- 28, for a purpose to be hereinafter set forth. A snodilicd form of this excmplilioation of the invention is shown in Figs. 9, l0 and 1], wherein the sides of the projecting l'lango 2| diverge slightly, and irojccting upwardly from .he llangc ".(i is a oss or projection 29. which is locatcd adjacent the tree extremity of the said llnngo and at a point substantially midway of the side, llangcs 27, the side walls thereof being substantially parallel with the llangcs .37. This form of protector is particularly adapted to be applied to bonds in which the body portion or cablcs 20 loading away'from the terminals 2], arrseparated innnc'liately at the point where they 'oin the terminals, as more clearly shown in l 'ig. 13. in the form shown in Figs. '2' and S, the flange 26 projects from the top of the. ring, ins-toad ol from the bottom. and these side llnngcs 27 project downward, and preferably extend a short distance below the base of the ring, as seen in Fig. 8. In this exemplification of the invention, the ring 25 is first. placed over the terminal 21, so that the flange 26 will rest upon the o )posite face of the bond body, as will be understood.

In Figs. .14 to 18 is shown a still further modification of this invention, and in this instanoc the encircling ring for the head of the terminal is dispensed with, and there is employed a ferrule, thimble or sic-eve 30, whic r ay be of an suitable construction, and may be sli )put upon the cables comprising the bond body, before the ends are welded, or may be a llat plate, which may be bent around the body of the bond at the point ,adjacent the terminal. This plate may be suitably shaped, if desired, to permit the samo to partially surround the tar-- minal 21, as shown in Fi s. 15 and 16, and may be applied by wrap nng or bending the same around the outsu e of the bod'v, as shown in Figs. 15 and lti, or bent as shown in Figs. 1' and 18, so that the body portion thereof will pass between the cables forming the body portion 20, and into a. substantially figure 8 shape, as seen in Fig. 15. In the forms of tho invcntion shown in Figs-1 to 13, the protector may be applied r-ithcr before the ends of tho strands of the body have. been welded into a homogeneous mass, or after this operation and before 'linal shaping or swaging. it is preferable, however, to apply the same 'ust before the tinal shopin or swaging, as shown m Figs. 1 and 9.

the forms where the projecting side flanges are provided, they may, if desired be bent down against the body of the-bond before linal heating. .h'tur heating, the terminals and the protector may be insertedinto suitable dies or shapvrs and upset or swngcd into thc desir d shape. During this swaging oi final shaping of the terminal, the protector or auxiliary rap piece becomes in corporatul into a. homoge s mass witlr the body and the terminal, thereby losing its identity (as shown in Figs. 12 and 13 and becoming an integral part of the bond and terminal, thus serving not only to protect the bond, or its strips, parts or strands, from scorching or burning and against meohanical injury, but also scrving to still'en and strengthen the parts at the points whom they join.

T he result obtained from the use of the forms shown in Figs. 1-1 to 18 is the same, exc-c )t in this instance, the protector is located only at the )Olllb where the body and terminals 'oin, amlsurrounds only the, bod portion. Thus, it will be see-.1 that wit such a construction, the ctlec'tivencss of the bond is greatly increased, asthe terminal can not work loose from the body. The movement of one in relation to the other is prevented nt the immediate junction of the terminal and the body portion, and is transferred to the end of the protector, where the wires are not at all injured.

It is to be understood that it. is not desired to be limited to the exact. construction and arrangement of the several parts, as numerous'ehnnges ma be made therein. without de )art-ing from t to spirit of the. invention.

Vhat is claimed as new is,--

1. A rail bond comprising a body portion having integral terminals, and a separate protector secured to the bond at a point. adacent the terminals.

2. A rail bond comprising a stranded body having its ends formed into terminals, and a separate protector plat-e surrounding and se cured to the body at the base of the terminal and projecting beyond the sidethercof. and in contact wit-h one of the faces of the body.

3. A rail bond comprising a stranded body having its ends formed into terminals, and a separate rotec'tor date surroundin and secured to tm base 0 ear-h of the ternunals and provided with lateral projections engaging one face of the body, said project-ions berm provided with flanges engaging the edges 0 the body.

4. A rail bond comprising a stranded body having its ends formed into terminals, 9. separato prutittol plate surrounding and secured to the base of the terminals, said Protrctor being provided with a lateral pro ecting portion engaging one face of the body, and flanges extending from the edges of t to projcuting portion and engaging the sides of name to this specification, in. the presence of two Sllbtllblllg min-asses, on this 13th day 10 of March A.
